TUNNEL.

Application filed April 8,

This invention relates to funnels, and more particularly to those usedin filling the radiators of automobile or similar engines.

One ofthe objects is to provide a simple and cheaply manufactured deviceof strong and durablestructure which may be easily introduced into thefilling opening of such radiators and supported in position to directthe rapid flow of water thereinto without danger of spilling the sameover the radiator, and without pouring any of the water down the usualoverflow tube located in such filling openings, the device having simplemeans for engaging and covering the open upper 5 end of said tube forthe purpose.

A full and complete understanding of the invention may be obtained froma considera-- tion' of the following detailed description, taken inconnection with theaccompanying drawing forming a part of thisspecification, it being understood that while the drawing shows apractical form of the invention, the

latter is not to be confined to strict conformity with the showingthereof, but may be changed or modified, so long as such changes ormodifications mark no materialdep'arture from the salient features ofthe invention, as specifically pointed out in the appended claim.

In the drawing, in which similar reference characters designatecorresponding parts throughout the several figures:

. Figure 1 is a side elevation, partly in section, showing the improvedfunnel in operative position in the filling opening of an automobileradiator.

Figure 2 is a horizontal the line 2-2 of Figure 1.

Figure 3 is a detail, vertical section, at right angles to Figure 1. y

The invention comprises funnel of ordinary construction having the usualtapered body portion 1, to the lower, smaller end of which there issuitably connected the upper, larger end of a tapered spout 2. These twomembers may be separately formed and suitably soldered or otherwiseconnected together, or they may be formed of a single blank of suitablesheet metal, preferably copper, suitably rolled and formed into shape.

Mounted within the spout 2 and in concentric relation thereto, is aninner tube 3 formed of the same material as the parts 1 and 2, said tubebeing of equal length with section. taken on taken 1926. Seria 1 No.10(l,631.

the said spout andhaving its ends located flush with the respectiveendsof the spout.

The lower orouter end ofthe inner tube which is adjacent to the smallend of the spout, is open, while the opposite end of the inner tube,which is adjacent to the reduced, lower end of the body of the funnel,is closed, as at 4., said closure disc or the like suitably secured tothe end of the tube.

A cross is centrally secured, in any desired manner, to the disc orclosure 4 of the inner tube, and said bar extends entirely across theupper end of the spout and has its terminals 6 bent upwardly to confo mto the tapered sides of the body portion 1 of the funnel, to which thesame are secured, as by soldering or otherwise.

The entire device, as thus constructed, may be cheaply manufactured andsold at a low cost, and all of the functioning parts being locatedwithin the interior of the funnel, there are no parts to be lost, brokenor impaired by rough usage around garages or similar places. I

In using the device the spout 2 is placed within the collar 7surrounding the filling opening 8 which is located on the top of allautomobile or other radiators, as indicated at 9, and the dimensions ofthe spout are such as to permit the same to snugly fit within differentsized collars 7 and to rest upon the top thereof, by reason of the taperof said spout, the drawing showing the funnel being supported upon acollar of maximum size, the upper edge of the latter contacting end ofthe inner tube 3 to be completely housed thereby, and as the funnel islowered to rest upon the collar 7 the end of the over-flow tube islocated a greater or lesser distance from the closure plate or disc 4:.

The width of the supporting bar 5 is somewhat less than the diameter ofthe upbar 5, formed of the samematerialbeing in the form of a -with thesides of the body of the funnel.

per or closed end of the tube 3, and thus offers a minimum resistance orimpediment to the passage of the water, as the same is poured into theopen, upper and wider end of the body of the funnel and, as there is acomplete, annular channel extending entirely around the inner tube 3,the full amount of the water may freely find entrance into theradiator,as' fast as it may be poured into the funnel, for the main bodyof the water follows the interior walls of the funnel spout. r

By reason of the complete encasement of the upper end of the over-flowtube by the inner tube 3 and the closure 4, no water may enter the sameto be spilled over the floor of the garage or other place, and when theradiator is completely filled the water will not leak out materiallybetween the collar '7 and the spout 2, but will rise within the body ofthe funnel and give due notice, whereupon the pouring is stopped and thefunnel gradually lifted when the excess water, in a very small quantity,will flow out of the tube 10 to the level of the upper end of theover-flow tube.

Many automobiles are built with the overflow tubes normally located inthe center of the filling openings, as illustrated in the drawing, andin such it is practically impossible to direct the flow of water in amanner to avoid pouring great quantities down said over-flow tube, whenan ordinary funnel or no funnel at all is used. The improved funnel ofthe present invention may be easily and quickly applied in position tofunction on cars of this type, while in other cars the overflow tubesare normally located at or near one side of the collar 7 for the verypurpose of allowing as little water as possible to enter the same uponfilling, and

in this latter class it is a comparatively easy I engines or motors, thewater being held' from spilling over the hoods or radiators thereof andflow tubes ofthe same.

What is claimed is A funnel for filling automobile radiators comprisinga tapered body portion and a tapered spout joined together alongitudinally disposed inner tube mounted within the spout and havingits ends flush with the respective ends of the spout, the Outeror' lowerend of the said tube being open to receive the free end of an overflowtube and the inner or upper end of the same being closed to preventwater from entering said overflow tube, and a cross bar terminallyattaohed to the opposite sides of said body portion and centrallyconnected to the closed end of the inner tube to support the same.

In testimony, as my own, I have hereto affixed my signature.
